<p>A valve which is arranged to output from a passage 12 a substantially constant-rate flow of fluid, notwithstanding changes in the flow rate entering the valve by passage 11, is arranged to provide an output from passage 12 which is variable with the static pressure in that passage. Thus when the valve is used to supply a controlled flow to a hydraulic control system an increased flow rate to the system is provided to compensate for increased leakage in the system resulting from a higher static pressure in the system.</p> |
